I live in a co-op which is run by an array of committees. Everyone who lives within the co-op is supposed to put in a minimum of 4 hours a month to those committees or other things not part of committees, but still needed (delivering newsletters, notices, etc.) Of course the co-op has mandatory committees like building operations, but we also have ones that cater to the more aesthetic side of human nature, such as parties, arts and crafts, as well as gardening. I am the head of the gardening committee. It consists of 6 or 7 people. We have two rooftop gardens. We do the planting in the spring and make them look pretty for the next season. We make decisions on whats to be planted. People who are not part of the committee participate by signing up for weekly watering schedules. We have herbs that people can pick. It makes the cooks very happy. For the most part, the gardens exist for the beautiful and calm setting. We have a lot of bees and wasps in the gardens. We also have the odd butterfly here and there, but usually only when there is no wind. I participate in the ORG & HPS seed exchange. We label certain seed packets with the word "BEES" so that people will know that bees adore these certain flowers and will plant them to help the bees' survival. Even though we live in a big city like Toronto, living in a co-op is like living in a small town. You usually know everyone who lives in your co-op.
